Lowering rear of car

I really hate to say this kind of stuff, but....

SS springs are made for drag racing. Your car will sit high, and even higher on the pass side. This is how they are designed. When you play with this ride height you void the whole (or most of) point of having SS springs.

In short... If you don't like how it sits, get the right springs.

What you want are the XHD or some other stockish spring.

This is how my car sits with XHD and front hangers flipped. 26.25" from fender lip to the ground. Im pulling off 1.8 60' times on the E70-14 redlines with no "From the street to the track" changes. Thats a Dana 60 with snubber under there.
